प्रश्न
Each of the three states of matter has mass. Explain with the help simple experiments – that each state of matter has mass.
उत्तर
Matter i.e. solids, liquids, and Gases have mass explained by the following experiments.
(1) Solid
Experiment: A solid placed on one side of the scale, causes the scale to tilt towards one side.
Conclusion: The scale tilts due to the mass of the solid, hence all solids have mass.
(2) Liquid:
Experiment: A liquid placed on one side of the scale, causes the scale to tilt towards one side.
Conclusion: The scale tilts due to the mass of the liquid, hence all liquids have mass.
(3) Gas:
Experiment: An inflated balloon placed on one side of the scale causes it to tilt towards one side.
Conclusion: The scale tilts due to the mass of the gas, hence all gases have mass.
